The invention relates to an interplanting and reclamation method of agro-fruits in a dump of an open pit
coal mine in an
arid area. The interplanting and reclamation method comprises the following steps: leveling lands; after land
ageing and leveling, immediately
sowing seeds, planting perennial leguminous plants and gramineous plants, serving as sowed plants, in a mixing manner, plowing once in summer every year, burying fresh
plant bodies into soils so as to increase the
organic matter content of the soils by virtue of rot, and then
sowing seeds of the perennial leguminous plants and the gramineous plants while plowing; planting local suitable fruit trees in lines after land being cured; after the fruit trees survive for one year, interplanting crops with height not exceeding the fruit trees between every two lines of the fruit trees. According to the interplanting and reclamation method disclosed by the invention, as in the land curing process, the fresh
plant bodies are buried into the soils so as to increase the
organic matter content of the soils by virtue of rot,
rhizobia of the leguminous plants is capable of fixing
nitrogen so as to increase N element of the soils, and roots of the gramineous plants are uniformly distributed, surface soils and the physical properties thereof can be better kept, the water and air permeability as well as the water and
fertilizer conservation of the soils are improved while
erosion is reduced, and the level of ordinary cultivated lands is reached.
